Modifying GRUB2 for LABEL= syntax

view full story

http://www.linuxquestions.org – Greetings all, After a recent hard drive replacement, I find that I can no longer boot my Ubuntu partition. It seems that Ubuntu set up GRUB to boot using the disk id, which is no longer valid. I've been using the old GRUB for a number of years, and have always used the LABEL= syntax to assure that the correct partition is booted. There is a dire warning in the /boot/grub/grub.cfg file NOT to edit it. With the old grub, it was just a simple matter to change the menu.lst file. What file DOES get edited to make the change for the new drive? Is there an easy way to get GRUB2 to use (HowTos)
